Coleman Mach 8330A5221 -- Carrier A/C Control Conversion Kit
Bridge the gap between your Carrier wireless remote ceiling assembly and a Coleman Mach rooftop air conditioner. This factory conversion kit provides the control interface components needed to make these two systems work together, saving the cost of replacing a functional ceiling assembly when upgrading or swapping your rooftop unit.
When an RV comes equipped with a Carrier-branded ceiling air distribution and control assembly -- including the wireless remote receiver -- upgrading or replacing the rooftop unit to a Coleman Mach model normally creates a control compatibility problem. The 8330A5221 Carrier A/C Control Conversion Kit is Coleman Mach's purpose-built solution for exactly this scenario.
Rather than replacing the entire ceiling assembly, this kit adapts the control wiring and interface so that the existing Carrier ceiling assembly communicates correctly with the new Coleman Mach rooftop unit. It is designed for installations where the Carrier ceiling box with wireless remote capability is already in place and the owner wants to retain it.
Designed by Coleman Mach specifically for this Carrier-to-Coleman transition -- not a generic adapter.
Preserves wireless remote functionality of the existing Carrier ceiling assembly after conversion.
Avoids a costly full ceiling box replacement when only the rooftop unit is being changed out.
Interfaces compatible Coleman Mach rooftop A/C units with the retained Carrier control system.
Carrier and Coleman Mach rooftop air conditioners use different control signal protocols between the ceiling assembly and the rooftop unit. Without this conversion kit, swapping a rooftop unit from one brand to the other results in loss of thermostat and remote control function. The 8330A5221 provides the interface to restore full operation.
This kit is not a universal adapter. It is intended for specific Carrier ceiling assembly configurations paired with compatible Coleman Mach rooftop units. Confirm your existing ceiling assembly model and your Coleman Mach rooftop unit model are covered by this kit before purchasing. Coleman Mach tech support can confirm fitment using your existing model numbers.
If you are replacing a full ceiling assembly rather than converting, Coleman Mach offers complete ceiling assembly kits and replacement control boards for their product lineup. For full system replacements, verify whether a complete ceiling assembly or only the control conversion is required for your specific rooftop unit model.
